The mirror adjustment is only enabled when the ignition key is in position I or II.
Memory Recall
Memory recall has three memory positions stored for the seats and exterior mirrors. The switches for this function are
located on driver's seat outer side trim panel. Pressing the appropriate numbered memory switch allows the seat to start
moving to the position appropriate to that memory.
When a memory recall is initiated, to limit the overall current consumption, only two-seat axis will move towards their
intended position at any one time. To minimise current load as the motors start, the initiation of each axis is phased with a
10ms delay between each motor starting.
The cushion slide and backrest will move first, followed by the cushion height and tilt. If the vehicle is stationary, the
memory recall will operate in a 'one-touch' mode, whereby the switch can be released and the seat will continue to move
to the memory position. If, however, the vehicle is in motion when the switch is released, then the system will operate in
manual mode. This means that when the switch is released, the seat will stop moving. In order to reach the intended
memory position, the switch must not be released until all movement has stopped. The instrument cluster will emit a
double chime to indicate that the recall operation has been successfully completed.
The following procedure will store a memory position:
Ensure the ignition key is in position I or II
Ensure reverse gear is not engaged
Manually adjust the seat to the desired position, using the seat switches
Press and release the 'memory store' switch
Press and release the desired numbered memory switch within 5 seconds
With the ignition key in position II, a single chime will be emitted from the instrument cluster to indicate that the store
operation has been successful.
If any of the seat adjustment or memory switches are activated during a 'one touch' memory recall, the recall will be
overridden and the seat will begin to move in the direction corresponding to the switch that has been pressed.
Both mirrors move simultaneously about the vertical axis first (left/right), and then, once all vertical axis movements are
complete, about the horizontal axis (up/down). To minimise the number of mirror motor's required, a method of sharing is
implemented, which dictates that all movement about one axis is complete before movement about the other axis
commences.
Mirror movement coincides with the following table:
Lazy Entry
Pressing the unlock button on the remote transmitter will initiate a memory recall. This feature is known as 'lazy entry'. If
the seat movement, memory switch or the lock button on the remote transmitter is pressed, then the 'lazy entry' feature
will stop immediately.
The memory settings are stored within Electronic Erasable Programmable Read Only Memory (EEPROM) of the memory
control module each time the ignition switch is cycled from position II to position I. These are the positional values that a
